How I can upload a file to amazon s3 using multipart. I have gone through the all the AWS site but I did not find the code for objective-c or swift.
Could you please any one share your code for understanding purpose.
Refer this document then you can write code for multi part upload.
he minimum part size for a multipart upload is 5MB.

I want to upload large files on S3. I know there is an option multipart upload by which I can upload large file in parts. I read the documentation (http://docs.aws.amazon.com/mobile/sdkforios/developerguide/s3transfermanager.html) but didn't find any code for the multipart upload. I have successfully uploaded a file on server as a single file but I want to use multipart for large file.
Thanks.
IF you're still looking for a solution, you can check out my blog post on this subject: Taming the AWS framework to upload a large file to S3. For large files you will have to skip using the AWSTransferManager as it uses cognito credentials which are limited to an hour validity.
For my Rails application, I download a bunch of files from a remote URL to my application. I would like to directly upload them to Amazon S3, without needing a form to do the upload, since I will temporarily cache the file I downloaded on the EC2 instance.
I would also like to retain the links to the files I uploaded so I can download them later.
I am essentially reposting the files I downloaded.
I looked around, but most of the solution seem to involve form uploading to S3 with a user.
Is there s direct upload solution?
You can upload directly to S3 using the AWS SDK for Ruby. The easiest way is:
require 'aws-sdk'
s3 = Aws::S3::Resource.new(region:'us-west-2')
obj = s3.bucket('bucket-name').object('key')
obj.upload_file('/path/to/source/file')
Or you can find a couple other options here.
You can simply use EvaporateJS to achieve this. You can also take advantage of sending ajax request to update file name to the database after each file upload. Though javascript exposes few details your bucket is not vulnerable to hack as S3 service provide a bucket policy.
Just set the <AllowedOrigin>*</AllowedOrigin> to <AllowedOrigin>specificwebsite.com</AllowedOrigin> in production mode.
I'm currently working on an project which has implementation of an external api, and this api requires the image in binary format. The images are stored on s3, my question is how do read a file in binary format directly from the s3 without using a temp folder on the local end, so that I can pass it as a body of the request, for accessing the image i'm using
(s3client.buckets[ENV["AWS_S3_BUCKET"]].objects[params[:url].split("amazonaws.com/")[1]].read)
Can anyone help me out.
Thanks In Advance.
I have application where we have posts to which we upload photos. I have implemented S3 uploading module using carrier-wave and fog integration which is successful. But when images are uploaded along with versions the original file also getting stored in the same directory.
Is there any way to configure a separate folder inside my bucket to store only original images and rest of the images separately.
I also searched and learned that operating with multiple buckets is not yet possible with carrier-wave.
Kindly please direct me on this. Thanks in advance.
I'm writing an importation function from a remote service to our app which uses S3. I connect to an api using OAuth as authentication, so every request I make I need to attach the token in the header. The attachments must be copied to S3 and the model is using paperclip.
I read the file from the api (say origin) with a GET method which returns a response with the body filled in with the content and the header with filename and other information.
Q: Now that I have the body of the file in plain text, how do I store it in S3 (destination) with paperclip?
Alternatively
Q: I could upload the file to S3 (destination) using remote URL(as described here), but how do I attach the token to the paperclip request to the (origin) api?
thanks
You need to create an s3.yml in your config directory... Here's a detailed tutorial in setting up paper clip with rails 3: http://doganberktas.com/2010/09/14/amazon-s3-and-paperclip-rails-3/
I would suggest you use a conversion tool to generate either a PDF or an editable document, then upload that to s3... Here's a good PDF gem: http://ruby-pdf.rubyforge.org/pdf-writer/ and even a railscast to help: http://railscasts.com/episodes/78-generating-pdf-documents
and here's an rtf gem: https://rubygems.org/gems/rtf
Since you have the raw data that should work.
